How do I solve this problem?

nexus9112 [7]

Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)

Answer:

Step-by-step explanation:

Equation: $4x+4y=20$

The slope-intercept form is:

$y=mx+b$

So, in the equation given:

$4x+4y=20$

$4y=20-4x$

Divide both sides by 4

$y=5-x$

Slope-intercept form:

$y=-x+5$
